REMOVABLE WINDOW CONSTRUCTION.

T 0 all whom it may concern:

Be it known that I, OTTO J AEGER, a citizen of the United States, residing at Columbus, in the county of Franklin and State of Ohio, have invented a certain new and useful Improvement in Removable Window Constructions, of which the following is a specification.

The object of this invention is to provide a window casing with movable devices so that the window sash can be readily taken out for the purpose of cleaning or repairing the win dow, said devices also adapted to serve as locks for securing the sash from unauthorized opening.

The invention consists in the construction hereinafter described and pointed out in the appended claims.

In the accompanying drawings-Figure l is a vertical sectional view with parts in full, of the left hand side of a window casing equipped with my invention, said view being taken from the interior of the building; Fig. 2

is a horizontal section on the line acz Fig. 1 looking up; Fig. 3 is a vertical section taken at right angles to that shown in Fig. 1, but viewing in elevation the side of the window casing and with the sash removed; Fig. 4 is a detail sectional view showing the devices for the attachment of the sash-weight cord as applied to the upper sash; Fig. 5 is, a top plan view of the same; Fig. 6 is a detail side view showing devices for the attachment of the sash-weight cord as they may be used on the lower sash; Fig. 7 is a vertical elevation looking toward the corner of the sash containing the devices illustrated in Fig. 6, the cord-holding device being in cross section; Fig. 8 is a detail in elevation illustrating how the weight cord is retained when a sash is to be removed.

As the construction at one side of the window sash and casing is a symmetrical duplicate of the other, it will suffice to describe particularly that at one side only.

In the views 10 designates the window casing. The casing has fixed in its side a sheetmetal strip bent to form two deep grooves or vertical pockets 10 and 10 suitable fastening devices 10 being passed through oppo site edges of the strip to secure it 1n place. Engaging loosely or pivotally the upper portion of the casing are two tubes or runways 11 and 11 that are supported at their lower ends on a common su port consisting of plate 12. Said plate 12 as connected to it a Specification of Letters Patent.

rod 13 extending horizontally under the sill inward toward and beyond the middle, where it is provided with rack-teeth, as seen at 13, to be engaged by a pinion 14. The pinion 14 is fixed to and turned by means of a shaft 15 provided with a handled crank 15, and the shaft is provided, with a small toothed wheel 15 to be engaged by a pawl 15 to lock said shaft when the tubes 11. and 11 have been adjusted to their normal position, as hereinafter described. The rod 13, is of course, suitably supported so as to permit horizontal movement, as by means of small brackets 13 The rack of the two bars like that designated '13 are formed to face each other, one being above the other with the pinion 14 between them and engaging both so that when the pinion is turned it oscillates the sets of tubes (11 and 11 at opposite sides of the window casing in contrary directions, as will be readily understood. The sash frames are each provided at their vertical edges with grooves 16 to slidably fit against or receive the tubes 11 and 11 The sash-weight cord of the upper sash is attached to a short wire rod 17 having at its end an eye portion 17 to receive the cord. The said eye portion works up and down in the tube, a slot, as at 11 or 11 providing movement for the shank or rod. The corner of the upper sash is cut or mortised out to form a horizontal seat for the rod 17, and said rod is secured to the sash by means of a turn button 18 swiveled in the sash by havin its shank 18 passed through a vertical ho e 19 in the sash, the end of saidshank having thereon a nut 20 to prevent it from being pulled out. By thus sinking the rod 17 below the upper surface of the frame, a complete closure of the upper sash is made practicable. lower sash is shown to be attached to a similar eye-rod, but in such case the eye-rod has attached to it a dovetailed slide piece 17 that enters and engages a part 21 secured near the upper corner of the lower sash. In either case it will be observed that the sashcords are readily detachable from the window frame.

To remove a sash, the lower ends of the tubes 11 and 11 are moved asunder by turning the pinion 14 to the left, and the sashes (if up) are drawn down as far as possible. The separation of the tubes 11 and 11 is sufficient to permit the withdrawal of the sash frames when thus lowered from between The sash-weight cord of the the tubes. When the weight-cord attaching devices (as 17) are removed from the sash, they can be temporarily detained in easilyreachable position by simply turning the rod or shank 17 into a lateral notch, as at 11 or 11 as more particularly illustrated in Fig. 8.

l/Vith this construction no parting strip is needed, the convexity of the tubes and the concavity of the vertical edges of the sash serving to properly locate and guide the sash. By properly tightening the tubes into the grooves of the vertical edges of the sash the latter are not only adequately held from rattling and made abundantly air-tight, but also from the possibility of being raised by unauthorized persons at the exterior of the building.

The facility of removal of the sash as provided by my invention makes it convenient to wash the windows at the interior of the building and does away with the necessity of getting out onto the sill and the consequent explosure to danger from falling to the side wal r.

What I claim and desire to secure by Letters 1 atent is:

1. In a removable window construction, the combination of a window casing provided with runways at its sides each loosely held at its upper end to provide a substan tially fixed pivotal point thereof, means for supporting said runways at their lower ends,

window sashes adapted slidably to engage said runways, and means for moving the lower ends of said runways towards and from the window sashes.

2. In a removable window construction, the combination of a window casing provided with tubular runways at its sides each loosely held at its upper end to provide a substantially fixed pivotal point thereof, window sashes grooved to slidably engage said runways, means for supporting said runways at their lower ends, means for moving the lower ends of said runways towards and from the window sashes, sash cords running in said runways, sash weights for the cords, and connections between said sash cords and window sashes, said tubular runways having longitudinal slots to receive said connections.

3. In a removable window construction, the combination of a window casing provided with tubular runways at its sides each loosely held at its upper end to provide a substantially fixed pivotal point thereof, window sashes grooved to slidably engage said runways, means for supporting said runways at their lower ends, means for moving the lower ends of said runways towards and from the window sashes, sash cords running in said runways, sash weights for the cords, detachable connections between said sash cords and window sashes, said runways having longitudinal slots to receive the detachable connections, and means on the runways for holding the cords when detached from the window sashes.
